UMBRELLA.

To all whom it may concern:

Be it known that I, ANDREW DORUSCAK, a citizen of the United States, residing at Lorain, in thecounty of Lorain, State of Ohio, have invented. certain new and useful Improvements in Umbrellas; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to umbrellas.

The primary object of the invention is the provision of an umbrella in which the rib braces are detachably connected to the staff in adesirable manner and in which the cover frame and staff may be brought into compact form to materially decrease the normal length of the umbrella so that it may be conveniently carried in a dress-suit case, satchel or the like.

A still further object of the invention is the provision of a foldable umbrella which is simple in construction, capable of being used in the ordinary manner and that Ina be conveniently and readily folded for transportation, and also one that may be manufactured at a minimum cost.

With these and other objects in view, the invention consists in the construction, com bination, and arrangement of parts, to be hereinafter more fully described in detail, illustrated in the accompanying drawings, which disclose the preferred forms of embodiment of the invention, to enable those skilled in the art to practise the same, and

- as pointed out in the claim hereunto appended.

In the drawings :Figure 1 is a side elevation of an umbrella constructed in accordance with the invention, the same being partly broken away. Fig. 2 is a fragmentary side elevation of the umbrella the same being partly folded. Fig. 3 is a longitudinal sectional view through the staff of the umbrella, the said staff being shown on an enlarged scale. Fig. 4 is a fragmentary top plan view of one of the rib joints on an enlarged scale. Fig. 5 is a sectional view on the line 55 of Fig. 1. Fig. 6 is a sectional view on the line 66 of Fig. 1. Fig. 7 is a fragmentary enlarged side elevation of the rib braces and runner the latter being shown in section.

responding parts throughout the several views in the drawings.

Referring to the drawings by numerals, 10 designates generally a staff or stick, the same being formed of separable sections, 11, 12, and 13, to the latter section of which is detachably connected a handle 14, which contains a suitable recess 15, in which is pivoted an extension piece forming a grip member 16, the said recess 15, being of sufii cient length to receive the grip member 16, when the handle 14; is detached from the staff or stick of the umbrella. Threaded in the outermost end of the section 11, of the staff or stick is a detachable ferrule or tip 17, the same adapted to hold or detachably secure on the staff 10, a crown or notched collar 18, to which are pivoted the inner ends of ribs comprising inner and outer sections 19 and 20, the same being of substantially U-shape in cross section throughout their length and these rib sections have their adjacent ends connected by pivots 21, so that the outer rib sections 20, may be folded outwardly and inwardly toward the inner rib sections 19, to lie in substantial parallel relation thereto.

It is apparent that the inner sections 19, of the ribs have their ends protruded a slight distance beyond the point of pivotal connection of the outer sections 20, therewith, so that when the latter have been brought into alinement with the inner sections 19, they will be prevented from breaking inwardly at their pivotal connections with the inner sections when raising the umbrella during the ordinary use thereof.

Removably supported by the ribs is a cover 22, the latter being centrally secured between the crown 18, and the tip 17, and has suitably secured at intervals along its free edge thimbles 23, which latter detachably fit about the free outer extremities of the outer sections 20, of the ribs so that upon removal of the tip 17, after the frame has been folded the cover 22, may be readily and easily removed from said frame.

Slidably mounted upon the staff 10, is a runner comprising a sleeve 24, having integral therewith at one end an outwardly extending annular flange 25, the same containing at intervals openings 26, detachably receiving pins 27, loosely connected to the inner ends of brace rods 28, the latter being pivoted as at 29, at their outer ends to ears 30, formed on the inner sections 19, of the ribs. The openings 26, in the flange 25, are so disposed as to permit the pins to lie contiguous with the outer surface of the sleeve 24, of the runner. Carried by the sleeve 24:, is a clamping collar 31, the same encircling the sleeve lying outside of the pins 27, and the terminals of this collar 31, are bent to form parallel ears 32, in which is engaged a set screw 33, the latter permitting the binding of the collar 31, on the sleeve 24, to securely fasten the pins 27, for preventing their withdrawal or release from the openings 26, in the flange of the sleeve. The sleeve 24, is elongated and provided with the usual slit in which is engaged catches 34 and 35, suitably mounted in the staif, so that the umbrella may be brought to raised or lowered position in the ordinary manner.

To fold the umbrella into compact form it is necessary to unclamp the collar 31, on the runner and in this manner the pins 27, may be detached from the runner thus freeing the brace rods 28, from said runner, which rods are then swung inwardly in parallel relation to the ribs, whereupon the outer sections of the latter are swung outwardly and inwardly toward the inner section 19, which will result in the folding of the umbrella frame. Now the sections of the staff 10, are detached to shorten the length thereof, which will permit the storage of the same with the folded umbrella frame in a grip or dress-suit case and in this manner occupying the least possible space.

From the foregoing, the construction and operation of the invention will be clearly apparent, Without requiring a more extended explanation and therefore the same has been omitted.

What is claimed is 2- In an umbrella, the combination with a staff having a handle and ribs pivotally connected to the staff; of a runner slidable upon the staff, brace rods connected to the ribs, an annular perforated flange formed upon the runner, pins carried by the inner ends of the braces and engaged through the perforations adjacent the runner and a clamping member detachably engaged around the pins and contacting with the flange to hold the same in binding contact with the runner.

In testimony whereof, I afiiX my signature, in presence of two' witnesses.
